For a second straight day, a No. 2 seed fell at the 2015 French Open. Roger Federer lost in straight sets, 6-4, 6-3, 7-6 (4), to No. 8 Stanislas Wawrinka after women's No. 2 Maria Sharapova lost to No. 13 Lucie Safarova on Monday.
Federer looked out of sorts at times during the match, especially in a second set in which he committed 15 unforced errors to Wawrinka's five and was broken twice. He regained his form in the third set, when the two men traded serves and kept each other from earning break-point opportunities before the tiebreaker.
The quarterfinal appearance was Federer's best in a major tournament since falling in the semifinals of the 2014 U.S. Open. He was eliminated in the Round of 32 during the 2015 Australian Open.
With Federer goes perhaps one of the best contenders to win the tournament. Federer was the last French Open winner not named Rafael Nadal, earning the title in 2009. As the 2015 draw currently stands, the quarterfinal match between Nadal, a No. 6 seed because of a poor 2015 thus far, and Novak Djokovic, the obvious No. 1, could be the de facto French Open final.
Wawrinka advances to the semifinals, where he will face the winner between No. 14 Jo-Wilfried Tsonga and No. 5 Kei Nishikori. All three have one men's Grand Slam final appearance, but Wawrinka is the only champion, having won the Australian Open in 2014.
